Thank the Almighty, no matter what the circumstances. It’s not just to do with wealth & good things. Thank Him for guiding you & keeping you steadfast. Thank Him for increase in knowledge, for the lessons you’ve learnt from hardship. Do this each day and He will grant you more.
FYI: You can be happy for your friends when things are working out for them and still be sad that things aren’t working out for you the way you hoped.
That’s not jealousy. You’re just human.
