When it comes to setting goals that are new, you need a plan, motivation and determination to get there. It is important you understand you "want to do it" instead of " Everyone else is doing it, I need to do it too". Keep your progress in check, if one way does not yield results look for another, allow yourself to make mistakes but learn from your mistakes. Try not to compare your progress to other, surround yourself with strong, determine and, positive people. This always make your journey easier.
It is hard to stay positive and strong at times, but we all have the ability to make it work, it comes down to "do it now or later?" Later never happens.
If you put the effort in, results will show. Give it time, stop making excuses, do more, talk less.
