There are two types of well-being, one is physically well and the other is mentally well. You have not specified how you want to be well. So I assume you are talking about being mentally well.
To be mentally well you must first be physically well. Because body and mind work together.
Never compare yourself with others. Be content with what you have.
Always be positive.
Spend time with family.
Do what you love every day.
Be careful in choosing friends. Good friends will keep you well.
Pray according to your religion.
Oil your wheels. And don't waste time.
Never forget greed, pride, envy.
Do not get angry but be patient.
Don't borrow but save.
Set a goal and work towards it relentlessly.
For now, if you practice these few things, you will be fine.
B. Be happy when someone sees good. And be grateful for everything.
thank you
