Drafting LoR Forum

[mysonx3]

Today I sent emails to some of my undergrad professors asking for letters of recommendation, and I received a response from one of them asking me to compose a draft version of the letter for them to make some changes to and submit.

I'm wondering what advice you all can give me on drafting it. Writing a letter recommending myself is a bit of an uncomfortable & daunting task for me, so I'm not sure how to go about it.
