It isn't easy to get rid of conflicting beliefs, but try these explanations:
1. You could try adding the phrases "in a fun, easy relaxed manner" (self happiness) and "greatest good of all" (happiness of other people) to your intentions.
2. You can also think of it this way: having money means being able to help others. You can't help anyone by being broke. You may be able to help others a little bit by making an average income. Think of how much you'll be able to help other people if you're making 100K or a million or ten million.
