I ve heard this phrase from a nice man and it actually sums up the good mood to spend and achieve goals well in your life.
We, All of us, set up some invisible barriers that do only exist in our spirit.
" I would like to run my own company but it is too hard, impossible!!" " I would like to date this girl/boy but he/she is too beautiful/handsome for me, simply impossible"
" I would like to learn this language but too difficult"
I can insure you that many people have set up their own company without money, dated pretty girls even they are as ugly as a dinosaure and some others speak 4 foreign languages...
