There's no better place to start learning needlepoint then by learning how to thread a needle. But fear not! The process is pretty easy to do on your own. If you need help, your needle threader is here for you. Remember, practice makes perfect.
Pre-COVID, I used to damp the end of the thread and lay it flat between my front teeth. I've since changed my ways, and thank goodness for that.
The key to getting your thread through your needle properly, is by making sure you are first using the right needle! Needles used for needlepoint are usually tapestry needles, which have larger eyes (the opening you thread through) and blunt points.
In terms of needle size, this is a personal preference, but here is a good rule of thumb:
Size 8-10 mesh -- Size 16 needle
Size 10-12 mesh -- Size 18 needle
Size 12-14 mesh -- Size 20 needle
Size 14-18 mesh -- Size 22 needle
Some thread will be different than others. Some are easier to thread, others harder. Some fall out easily, others don’t. Some fray at the end, and others will stay perfectly normal. There is a learning curve, and you will decide how you like to work and what thread you like to use.
