What is the limit of your capabilities?
How many projects can you manage?
How far can you run?
How much love can you give?
A better question is: when is the last time you tested each one?
It’s not comfortable, but, it’s not supposed to be.
You’ll find that, once you accept that pain is not only bad, but, also good, the limit you set in your mind is something which you set – not something that is real.
