Desire and attachment is human nature, that's what we know. On the other hand, it's also true that we are capable of coping with any situation. So when it comes to having a little control over our desire, attachment and need, it's totally possible!
There's something inside us that always desire to have more. A better life, a new car and, whatnot! When we don't realize the negativity of this force, we fall into the trap of our own minds. It's not easy to get over it but it's not impossible too.
Let's see...
Understanding the deeper meaning of life can always help. The more we climb the mountain of desire the shallow our inner peace will be. Also, understanding that materialistic things can only satisfy our earthly feeling, not it can bring peace and fill our spirituality.
Learn to not attach yourself to 'things'. It can be people and materialistic things; anything. It doesn't make us selfish or heartless but more strong to refuse the negative force.
Break the chain of 'desire'. When you stop thinking 'if I have this I will do this or that' you automatically take control over your thought process. Thus it leads to having control over your unnecessary desire.
However, it's hard to think these ways. Because we learned to live like this and our surrounding also forces us to. Take a moment to realize, what race you are running and for what cost. At the end of the day, no materialistic thing or unnecessary desire can satisfy us. It only leads us to 'have more'.
Step back from this and try to see the true meaning of life. You can give more and have more peace in yourself in these ways!
