He was 100% right; I can tell this from my own experience. At one point in my life, I was much committed to a goal, that I almost forgot I have a family who love and yearn for my attention and yet I ignored them and totally focused on my goal. Guess what? I failed to achieve it; then I felt totally ashamed of my behavior towards my near and dear ones and totally abandoned my outside responsibilities; I went from one extreme to the other extreme: both are problematic and are prone to failure, depression, and/or anxiety. At another point in my life, I ultimately achieved something, something of a kind that I have been waiting for so many years to get, and this is the first time I got something like this. But when I achieved itm I felt relaxed and slowly but surely retired from my responsibilities, since I already achieved it! I deserve rest now. However, internally, I was not happy either, because I was questioning myself: does it worth so much struggle, pain & sacrifices? I mean, I didn't really enjoy much of the process I had to go through to achieve that goal, most of the steps directly conflicted with my personality type (I had to do a lot of acting to conform with the crowd around me though I didn't like those type of people), yet I forbore for the sake of that goal because I was thinking: how awesome that goal would be! If I achieve it, its joy will definitely let me forget about all those sacrifices, etc. But the opposite happened. I felt that the joy was momentary, as compared to the actual pains of the process. In summary, I realized that if you don't like the process, no matter whether you achieve your goal or not, you won't be satisfied/fulfilled/happy. So love what you do rather than loving/focusing on your goals.
