I saw many people who:
1. Decided to have some goal
2. Failed to achieve that goal
3. Got badly disappointed
As we can see, the disappointment could have been avoided if step 1 was never taken.
In other words, dont have goals or attachments.
I know that your attachments are your weakness.
Think of it this way.
If you are addicted to drugs, you will suffer if you dont have drugs.
But if you never get addicted to drugs, you dont suffer when drugs are no longer available.
An attachment is a need for something. When you create a need for something, you will suffer when you lose that something.
But if you have no need for something, you will not suffer if that something is no longer there.
So,
the pain from losing something
is created by our need for that something.
So to remove pain, one must remove need.
But how does one remove need?
Does one simply accept different needs that are easier to satisfy?
