We are often prisoners of our own minds. Limited vision and limited imagination keep us from achieving often simple things. The simple thought “I can’t do that!” can stop you before you even tried.
Our minds can ‘think’ about reality and possibilities. To a certain extend we can envision the future and personal limits - but not everything our ‘common sense’ tells us is ‘real’ and the true limit of our abilities.
So free yourself and experiment with your limits. You can surprise yourself, you can grow and learn new stuff. Only false limits can really stop you more than anything!
