To reach your goal you need to know what is required to achieve it. Once you have found the activity you have to do the next hurdle is making a habit out of it. Practising a certain activity for 21 days allows you to consider it as a habit, that will get easier to maintain. After having created it as a habit you are going to less or even no discipline to continue on the same route. If you have been exercising for 5 years consecutively it will be unlikely that you are constantly considering not to go workout.
After managing to transform the activity into a habit you can turn your discipline to work on a different part of your life. For example if you first managed to add in working out into your routine you can implement your discipline in your food intake. Once that you are so used to take care of the food you are eating you can start meditating every morning. After implementing this you can continue by improving your second language by woring on it every single day.

Without even thinking about it like that you have build up your life and seemingly you have obtained an incredible level of self discipline.
Most people consider themselves as being badly motivated and/or low self disciplined. However everyone can improve on them as long as you put work into it and keep going for it.
