Self satisfaction alone cannot determine if a desire or action is positive or negative. The demarcation between a positive and a negative desire or action is not whether it gives you a immediate feeling of satisfaction, but whether it ultimately results in positive or negative consequences.
If you make a choice that doesn't please your mate, your friends, your mother, or whoever, the world will not fall apart - the people who truly love you want you to love yourself.
The best way to not feel hopeless is to get up and do something. Don’t wait for good things to happen to you. If you go out and make some good things happen, you will fill the world with hope, you will fill yourself with hope.
