1) I believe that online learning at the moment is not able to replace the main one, because with such training, the quality of education noticeably decreased.
2) Digital learning will not able to overcome cultural differences, because only the form of education will change, but the people being trained will remain the same, an individual approach is needed for each nation.
3) You can develop self-motivation by encouraging yourself for each completed step, for example, giving yourself to play your favourite game after one step for half an hour, this will give motivation to try.
