"There’s no perfect workout; find something you can enjoy and make sure it will fit into your
schedule. Set a specific goal and small milestones within that goal. Then, give yourself a few
reasons why you are doing it. On days you feel unmotivated remind yourself of that goal and
realize that overcoming these small obstacles will get you to the next milestone, and ultimately
your goal. Once there, set a new one and never stop challenging yourself!”
