I am not an ambitious person

When i was starting my career my end goal was to be the head/director/lead in the field I belong to. Everytime our big boss then would talk in front of the big crowd i'd always say "someday I will be like her."

After 12 years in the corporate world and in the same field, I realized that I am not am ambitious person. I thought I'd be happy once I reach that level but now that I am still a few steps away from that, I already know that I will never be happy, that it's not what I want. The rest of the world thinks that I am competitive. No I'm not, I just want to give my best in whatever work/task that is given to me. I think the right word is "responsible." Management gives me this role therefore I perform to what is expected of me. But if asked if I'm happy? No. I feel it's an obligation.

What makes me happy is balance in life. I dont want to work on weekends. I dont want to stay up late just because of work. I want time for myself and for my family. I want time to do others things I love such as sports, exercise, watch movie, watch TV. Once I have my own family, I want to spend time with them. These things make me happy.

I guess priorities in life change once you grow old.
