Absolutely, it's not that difficult to learn only 10 words a day. The most difficult thing is to maintain what you have already learned on the previous day. But difficult doesn't mean don't do it because it will be useless. In my experience learning a new language, what matters is, how durable your will to learn your target language. By learning only few words a day straight without skipping, there is no doubt that in the long run ( like a year ), you'll remember at least 1 word, which is still can be regarded as an achievement. I was talking the worst case. The best case scenario is you'll remember all of them.
But that ( learning a sum of word a day ) is my learning style. I heavily relying on dictionary apps, I learned how to use the dict apps efficiently and correctly. As the time goes by, now I know how to use the dict faster, with a bonus result that somehow, because I looked for the same word over and over again for hundreds of time, it automatically saved into my brain as a cache data, which sometimes made me remember the words that I used to look for.
