When I was a little boy, I read a story in comic book for children.
It goes like this..

“Long ago, there was a professor and his students. He taught to his students according to their intelligence.
Therefore, some students had chance to learn more than one subjects so they possessed  many skills.
There was a least intelligent one among outstanding students. Meanwhile, his friends were discovering more than one skill, his capacity was limited and only able to learn one learning.
So, the professor taught the easiest one to raise it as his career. That was pottery.
After all school years passed and professor believed his students were ready to go into realy life .
And then each and every one returned to their nations and applied knowledge they acquired in university.
But, the students who had learned more than one skill were not quite successful as they anticipated.
But, for the stupidest student who learned only pottery.
He didn’t learn other things, he only did pottery everyday and eventually he became a professional and getting rich by making pots.

When other students heard about him, they complained to their professor that why he didn’t teach them the way to rich,why the stupidest one became more successful than any of us.

The professor didn’t give an answer immediately, but asked his smartest student to climb along a bamboo tree in his backyard.
When he was on the tree, the professor asked other students to shake the tree hardly so that he could fall off.
The guy on the top of tree jump out to another one when the branch he hold was shaking.
When he reached on another , his friends  on the ground did the same way to tree he was holding.
He was moving from one tree to another whenever he almost fell off until he realized to hold a strong and bigger tree to keep stay on top.

Finally, the professor told his students that you will never be stable and rich if you are switching your career one to another..”

That story always remind me of the work what i am doing.
I am not smart , but .. still doing many things. And no profession anywhere.
