Start with the one you are sure you know how to do. Then do it! 1 done!
Finish the one that is almost complete. Do it! 2 done!
You can do anything that you set your mind to - and only the first one is hard - after that, it's all gravy.
What a wonderful gift you have been given - accept it and learn everything it has to offer.
Wow that sounds so preachy. Didn't mean to, sorry.
