what is more important for survival - being true to self and the word or to be under the cover and follow the worldly trends?

Being true to oneself sounds good, and IS good.

Though, I have a question: Does everyone agree on what is meant by "being true to self"?

In my opinion, "being true to self" is admitting to ourselves our mistakes, errors, insecurities, fears, weaknesses, and most definitely, our strengths as well. The central idea is to never lie to ourselves.

For example, we might not admit that we have certain holes in our expertise. We do this mostly with certain types of people - usually the easily excitable kind or the ones who are overly critical of us and try to take advantage of us if we admit our weakness(es) or even those who look to us for leadership. We try to always project a sense of confidence, expertise, knowledge, and strength. 

Yet, though we maintain (or try to) that projection/aura of capability and invincibility, we must never lie to ourselves. If we have holes in our knowledge or capacity, we must be aware of them and compensate for them by filling those holes or by including in our team(s) such people who can cover that gap. If we forget to compensate for our weaknesses and/or conversely neglect to rely on our strengths, we are setting ourselves up for setbacks.

This does not mean that we should be fearful. Rather, we should be courageous - carefully. :)

In conclusion, I firmly believe that we should believe in ourselves but we also should NOT take ourselves too seriously. :D

we r true every thing will be true i belive

Agree to Mr. Srinivas, Follow your own instincts.. Be true to your self and half of the problems are solved.

“Shreyo svadharma vignah parartha swanishtah
Svadharma nidhan shreyah paradharma bhayavahah”- Bhagatvat Geetha.

Do what you believe in strongly and true to urself.  When you have the ability to follow your own instinct, following someone destructive for your growth.  True to urself.

WHEN ONE IS TRUE TO SELF,PEACE AUTOMATICALLY COMES TO HIM/HER.

Himanshu am with you in this. you need to be loyal to yourself first if that's the case you are loyal with the rest of the world but if it's reverse you can't just satisfy youself by keeping the world happy

Being true to oneself is most important because one can not cheat oneself. if that is done one is doomed.

I agree with George ..... 

Be true to yourself don't wear mask for others....  :)  

Dear Sumita, there is an one word answer to your debate is "enlightenment". Buddha, Jesus, and avatars of Vishnu all were enlighted being on the earth. until you enlighten yourself you can never be happy in your life. Many occasions you have to wear masks at office front. That is your post and position to carry out the jot as described by the management. but never loose your identity in your activities.
