Here is an excellent little volume intended for a year's use but can be finished much quicker. Some are very short [a few sentences] while others are about a page in length written by "worthies" of the past [Spurgeon, Brooks, etc.]. A few folks have complained that some of the devotions are not good while others are great but I have found, in over 40 years of ministry, that often it is our attitude, our spirit, our mood that can make the difference in blessing or blah. I have read one on one day and not been impressed but read the same one a day or two later and been deeply moved. In any case, if one is not your cup of tea then just keep reading until you "get the blessing." Obviously God has used these quotes to bless others, why not open yourself up to what God has for you?
I finished this years devotion in a little over a month, reading whenever I sat down in the seat next to my kindle. I didn't read it so fast because I wanted to get it done but because I enjoyed them so much. I hope they will be a blessing to you as well.
