A verbal commitment is the same as a handshake.
You are only as good as your word- when you give someone your word it is of the utmost importance that you follow through and do your best to keep your end of the bargain.
You want a reputation that is solid and one that people can trust and the only way to have that is to keep your promise- every time ! Not once in a while and not to just a few but every time and to everyone.
A verbal commitment is the same as a handshake and a handshake should be your bond.
There will be times that for reasons beyond your control you may not be able to follow through but if the effort is there then that will show through.
Take it serious people..after all it is YOUR reputation at stake .
