I am talking about ideas for posts / sites / whatever. I just came back from school (ya, still doing school at 24), and had a great idea for a blog post here, I even thought about a catchy title! Now I am here, sitting behind my desk and guess what… Idea is completely gone! Damnit!
Write good ideas down immediately
Before you know it, you will not remember them. I hope it comes back in a sec, but I don’t count on that because I am heading forward to work on a couple of other sites with a totally different topic.
Don’t be a fool like me, write them down on paper, in your mobile, on your desk, whatever is in front of you 
Writing things down is the best way for me to learn things and keep me focused on what I have to accomplish throughout the day. I have a note on my PC and a piece of paper next to me all the times.
Yes, next time I will wirte it down instantly
