I've+heard+it+all+before

I ran out of time!
 * make time
 * timetable it
 * replace something else with it

I forgot how to do it
 * ask someone
 * talk to, phone, email the person who showed you in the first place
 * practice the new thing you learnt that same day

There are too many other things happening
 * make this happen
 * replace something else with it

I can't do it
 * let's set an easier task then
 * let me show you
 * find someone to show you then you show someone else

I can't fit it in
 * do it instead of rather than as well as

I haven't done it
 * well do it then

I'm not sure that it will be useful
 * try it
 * find some usefulness in it

I don't know where to start
 * go to this website
 * write down these steps
