So take it easy. Learn while you earn. The motto of this site, which is incidentally a knowledge sharing and educational site, is Learn to Earn, Earn to learn.
So, stay, contribute, learn and earn in the process.
Thoughts exchanged is knowledge gained.
I will suggest you to start your contributions in the sections of your interest and try to keep the quality and content as per the best of your capability. Do not attempt to copy and paste any information from anywhere and write the things in your own style. This is very important as there are some apps and softwares which quickly find the copied contents and you will be in problem if it is so.
My advice will be that you stay here for a long period and learn the subtleties of this site and learn and improve your knowledge here and slowly you will be earning some money also here. All the best.
Knowledge is power.
