I have seen many people who are just lazy, even I act like a lazy sometimes. The reason behind that is just that they cannot help it. Here are some approaches which may help you being proactive.
1. Don't try to be perfectionist and don't leave everything just because you cannot be perfect in that.
2. You have to take risk always. Don't leave anything just because you may do mistake. Go for it.
3. Increase your expectations. Do not stick to what your are today.
4. Whatever you want to do, do it now.
There can be many other approaches for being proactive, but these four are really very helpful. Try it!
