Have no expectations

The more you expect, the more you desire. The more you desire, the more you long for. The more you long for the more you want it. If perhaps nothing will happen, then these things will lead to more disappointment.

So expect nothing and you will have no disappointment.

Do not demand of others for what you can do yourself

Sometime in your life you would "relegate" responsibilities to others so that you do not have to do it. That is not relegating that is shirking responsibilities. If you can do it yourself with nno fuss why not do it and be done with it.

Give responsibilities to others only because you feel you have nothing to bring to the table or they can do it better than you can. If they can achieve it but won't don't make demand for them to do it either or they will just feel pressured and leave you alone.

If someone make demand on you when you do not have to do it, do you not feel as pressured. So when giving responsibilities to others do it with a light heart and no expectations so that you will not be hurt by it nor other feel pressured by it.
