Thank you Teresa for starting these discussions that let's us practice our English while talking about different issues.

I must admit I am not competitive at all and sometimes I feel I am not made "for this world" (which is very competitive), I try to do my best and do things better but this is something about me, not comparing to others.

First of all,  it is very hard to define "competitiveness" for me. It suggests there is no possibility to assess "competitiveness" without relevant measurement. I would have to say a person's advantage is in another way his disadvantage. For example, if you are very focusing on your work and seriously studying on your profession, in a way, you are not very easy to relax on some social cozy occasions. I have seen a couple of specialists who are very adept in their skills cannot have good relaxation on some of social occasions as more often than not, they are apt to concentrate on their specialty even that is a casual place to have fun. You might say you can balance both of them as many people think, but a bleak fact is the majority of the people are not invincible or not strong enough to defeat all hardships.  

I am not so competitive as some of others in a way but I have faith that God must make me become a competent man in a sense.
