I'm Tired All The Time And My Doctor Says My

I'm tired all the time and my doctor says my heart is skipping a beat. I smoke 2 packs of cigarettes a day and drink 6 caffeine drinks a day also. My have shortness of breath also. I take blood pressure pills and the other day my blood pressure was 150 over 100. I know I need to quit smoking and get more exercise but I just or don't have the drive to do it or I just don't want to.
Can you give me some tips or advise that might help me to have more desire to stop smoking and start a exercise program??
