Self Improvement Made Easy

I hate it!!! I make goals, and I don't accomplish them or at least I don't get it done in time. This has costed me a lot, from money to even good grades to even really good Trading Cards I wanted. Can someone give me advice/tips on how to stop and prevent procrastination/laziness once and for all. What's even worse is that people are going starting to notice that I'm getting lazy and I'm not prioritizing right. I spend so much time on nonimportant stuff. Someone help me!!! I'd really appreciate it. Thanks.
