Everything little thing you do matters. If you do 100 negative things in day, your day will be negative. If you do 100 positive things in a day, your day will be positive; pretty simple, but not easy!
Goals are reached by taking small deliberate steps each and every day. You gain momentum and confidence without realizing it and before you know it, you are better than you were. (eating clean, saving the extra dollar, working out when you don’t feel like it) The same can be said about negative actions. (Having the extra beer, buying something you don’t need, complaining) Just like Newton’s First law: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Ask yourself: Which direction do you want to go in?
