Using fonts on Blogger

Hi all, new to using the community, new to learning graphic design & already had someone in another forum tell me I'm too old to be learning graphic design (I'm 62). I'd like to use a font or two that I've found here on my blog & I use Blogger. Is there a way I can do that to write my posts using the fonts I want from here, or have the posts appear on my blog w/my desired fonts? Forgive my elementary question & I appreciate any help/suggestions.
