Find your "WHY?"
It could be anything! No matter if it's getting stronger, be healthier or just to look good. If your "why" is bigger then what you're currently doing then you will make results. When you feel your why then you have to find something that you can stick to. Ask yourself "Can I do this everyday for the next 10-20 years?" If you can then you have already reach your goal. The goal will change over time and that's a good thing to remember.
The hardest thing for me was accepting that it takes time. Just do the small things everyday and it will be a part of your life. To DO something is way better then just thinking about it. Thinking about it will NOT get you where you want. You have to take action. You have to find a way that makes it easy. Something you can stick to. And then it's all about living it fully. If you do right everyday the results will come sooner then you think.
