As mentioned above, age should not be an issue. It took me 27 years to finish my bachelor's but was finally able to do it. I also know an 80 and 90 year olds who have done back to finish theirs that they started 60 years prior. It is not about age, it is about your desire and willingness to reach your goals.
It took small steps, breaking things down into manageable pieces, to get there when started back again. Find, even if it is 15-20 minutes or perhaps as much as 30 minutes at a time if up to it, to work on it and you will get there, know it and believe that you will. As long as you commit to SOME time (even if 10 minute increments to get started) and doing the work, you can do this! Wishing you well!
