What you describe is true. Also, one thing to keep in mind is that some people like to start at full blast with Advanced workout splits or exercise with too much intensity in the first weeks and then burn out. What I'll recommend is beginning with something small and manageable that gives you a sense of accomplishment and momentum. That's how I got to where I am today.

Also, plan beforehand and keep track of the good things you do to motivate you. Great article and I hope people can understand this message.
