"Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously."2 Corinthians 9:6
When you are in love with stuff, you will go through life with a closed fist. But if you keep your hands open, you will experience more contentment and joy than you ever thought possible.
If you want to live with open hands, you may need to begin with a bowed knee. Ask God to help you unclench your fist and He will do that for you.
Then, thank Him for all that He has given you and ask Him how you can use what He has blessed you with to be a blessing to others.
