Why do many not follow their dream jobs?

Why do so many people not follow their dream jobs? What are the real or perceived limitations preventing them from doing so? :)

A certain value set has been engraved in the mindset of people on what is real and what isn't.
We all set barriers to others, and ourselves through laws (personal cultural values). Very few are willing to go against what mama, papa or friends and external social families, which includes religious barriers said.

The fear of failure is so engraved subconsciously through bad parenting (fit in or I will punish you tactics) and sibling rivalry (comparison based judgmental minds), that many resign their faith to hopelessly following others and what society views set as the example but no one tells them that every human being has limitations due to circumstances needing urgent handling (eat, protect), time and many facts are buried in the sands of time on how someone did it! Nothing is new nor will forever be hidden. Clearly egomania (not willing to shadow an example to find the loopholes) stands in the way.

We like to listen to myths and seldom probe to bring out facts to see the truths buried in mysteries. Break it in your mind to see the loopholes (at least there is no lord over your mind except you allowed someone to rule over it) and bend it (develop the innovation that transition the old to the new). Many hold on to the old even when it is choking the life out of them and the society.

Scientific knowledge is limited and ever renewing its previous stance. How much time does one really have to know it all? In partnering and socializing one can get a lead! Science deals with 2 major areas mind and matter! How many employ themselves? Man innately is lazy except he is pushed, be it by positive or negative motivation! Many people don't dig deep or explore wide.

• In the hierarchy of needs! The first 3 which is physiological, security, and belonging levels are the basic levels that sustain life.
• The other 2 stepping stones are "Self esteem which is achieved through self actualisation" (level of needs in the lifecycle of a person or a business in its endeavours towards growth) is what most humans struggle with. These are also drivers of innovation and evolution which exists in the minds of self and economic leading people.

Very few people want to be conscious of life and hence find it difficult to achieve their goals. Lack of interest in the world and their inner self is also a factor where people get stuck in finding their strengths that would reduce the weaknesses the world has!

There is also this habit that developed due to growing in the warmth of the family's arms. People get used to being given so they think their job is just to take. All this policies on child labor etc. has been staged to such extent that we have made cripples out if kids and this self serving ideologies of inheritance that has made kids turn to adults for every thought and thing accepting that they don't need to find themselves within the walls of life that their parents went through! same parents who fought for their comforts have now trapped their kids in it.

The Purpose of life of man on earth is clouded with the world’s noise! If only they knew that all that noise is just other people fighting for their space and they should join the dance or dream up a new way!

PS: For what it takes now in the world that we live in to market and promote self or a business is becoming harder and harder regardless of available marketing tools, Strategy and tactics skills is none existent in most, apart from available resources there is also creativity skills and character to withstand the constant bashing from competitors who use underhanded manners in sustaining their market share "like bad publicity" how ever that can also be a way out. What does it take to keep being there? An almost animal instinct is to be adopted when facing those who choose to be either docile or aggressive. There is something called Gorilla tactics and that is not just time and energy consuming but demands intensive capital that a startup seldom has.

What is a dream job? Coming from where I have threaded it is interest in seeing oneself grow as well as passion for those whom I have employed myself to serve.
