promises and plans must be put into action, otherwise they are useless
the road to hell is paved with good intentions
to give up something harmful that you have done for a long time
kick a habit
a job where there is little or no chance of career development and advancement into a better position
dead-end job
it is successful and produces good results
bear fruit
start to act or behave in a better or more responsible way
turn over a new leaf
it takes a long time to do a job or task properly, and you should not rush it or expect to do it quickly
Rome wasn't built in a day
to start a new life
make a fresh start
if you say that, you mean that somebody is trying to do something which is too difficult for them
not to bite off more than you can chew
make a start
get the ball rolling
to make a lot of effort to do something
put your heart and soul into something
