Now, what would happen if I complete the task?
1.You'd be a developer.
2.If your addon has enough quality, other people may like to collaborate with you to make a team to work on an idea
of yours...
My advise is... practice, practice... until you have a good addon.
Do not release your first addons.
Wait a bit until they are really cool for the most demanding users.
Even then you may get mixed comments, some good, some bad, some trolling or flaming, etc.
But since you are a dev because you enjoy it, that will not stop you.
