If one of your New Year's resolutions is to improve your writing skills, you won't need to roll out of bed by 5 a.m. to go to your local gym. You can keep this resolution anywhere.
Like any resolution that's worth keeping, improving your writing skills will take some effort. The good news is that it doesn't need to be cumbersome. Learning how to write well takes practice. Learning how to have fun while writing takes practice and a bit of creativity.
