You should be proud of what you're doing, but not conceited. If you can't be proud of yourself, you're a failure. And discipline. To do anything in life you have to have discipline. To accomplish anything, you have a goal, challenge yourself, and work until you accomplish that goal. Practice what you preach.
Jack LaLanneWhatever you can handle, it's up to you. Pick something where you are going to do it to failure--in other words, where you can hardly do it. That's the key. So many people will just take five pound weights and do something 10 times. What are they getting out of it? Nothing! Say you are going to build up your bank account. If you put in a penny a day, it's going take a long while. It's the same with exercise--the more you put into it the more you take out.
Jack LaLanneIf you're tired and pooped out all the time, do you have love and compassion in your heart for your fellow man? You don't even like yourself!
