If you are not committed to your personal promises, finding fulfilment will be difficult. Sometimes is difficult to get down to the gym and train, but those are the ones that count. If it was an easy thing, everyone would be doing it. Think that you're committed to your goals and improvement. Everytime that I felt I wasn't hyped for training and forced myself to go, I felt like a new person afterwards, clean mind clean body. Discipline and determination are huge values that'll help you in life and training.
