Don't close the door to your own happiness. Don't let bashfulness or shyness stop you from enjoying your well deserved riches.
Motivation is not an endless stream that goes on forever. It's a muscle that you have to exercise on a daily basis. Just as a battery needs to be recharged, so does your motivation. Don't get upset or frustrated with yourself when your motivation runs low - you just need to recharge it. It's the same for all of us.
If you can't get people to listen, save those clever ideas for a time when you will be heard.
