Through most of my life, I have struggled and chosen to power through, rather than seek out support...
I am the same. What I have achieved till today is thanks to my powering through in life. Well, there were not more people willing to lend a hand of support to me anyway.
I don't like that kind of person who is a burden on anyone. We have a phrase;
If you have a nail, then you can scratch your head.
Which means that do not wait support from someone before getting into something.
