G-D created you so you can never say I can't because you do not know the extent of what you are truly capable of .Only the manufacturer knows the true, full capability of his/her product.
We only say we cant
Due to the hypnotic dance of the herd that tell us what we can and cannot do

We want things to happen when we want them to and dont realize that G-D has the stopwatch not us

We are too lazy and /or too fearful to venture out of our comfort zone

We limit ourselves by judgements and assumptions and thus do not see past them

Let us not have the hubris to act as if we created ourselves and bow to the wisdom of our "Manufacturer, " Creator who knows what we are capable of and puts no cap on our potential,abilities etc at times we just have different pieces to play with but we remain unlimited.
You can always takeit higher you have G-D within
