Truth is a universal idea, but it is only universal in that it may be one truth here, another there, another there, and so on. There is no such thing as The Truth. What truth really comes down to is a belief. If you believe it, then it is true for you, regardless if others agree with you or not.
It may seem that a majority lives in the truth that life is hard, that it is hard to succeed, and that the pie is only so big and there is only so much to go around, and so on. These are among the myriad of ways that we limit ourselves by what we choose to believe from whatever source that belief came to us.
Limiting beliefs can feel very cozy and comfortable, and they can often find agreement with others to help us strengthen our position of outside limitations as being the norm. We can also decide to change those limiting thoughts and beliefs and cross the Pyrenees to the other side at any time.
Maybe it is time to let go of some of those lingering limitations.
