Today was a difficult day. I had a lot of work. It was a difficult project. I did not know how I can make my drawing more better. When my boss came in, he told me what I must work more faster. 

And I did it. :)))

Today (Thanks for your help in the fight against mistakes)--

but I would just say: Thank you for correcting my mistakes

Today was a difficult day. I had a lot of work. It was a difficult project. I did not (didn't) know how I can make my drawing more to make my drawing better. When my boss came in, he told me what I must had to work more faster and so I did. :)
And I did it. :)))
