It can be challenging to always remain motivated. Motivation can wear off. Having motivation alone is not enough. It can get you started, but it can’t always keep you there. Instead, use your initial motivation as a tool to help you jump-start making something into a “habit.” When something becomes a habit, it becomes a part of you; you can’t help but stick to it.
Want a better body? Get motivated to make a change right now. Then, practice this new habit for at least 21 days if you really want it to stick! (That seems to be the "magic" number.) I know you can stick to it for at least 21 days if you want it bad enough!
No excuses, no 50% efforts. If you want to build a better body, you are going to have to go through a whole lot of sweat and body-burning-feeling. You will have to LIFT HEAVY. You will have to LIFT FREQUENTLY. You will have to EAT RIGHT and you will have to do all this for a long period of time (MINIMUM 3-12 months depending on your goals). Thereis no short cut.
You will have to give up those habits that haven’t served you well, including that habit of changing your mind every other day. Nothing beats a good plan, consistency and dedication. Nothing.
