So take for example learning French. Unlike some people, languages are no longer my top priority.
However I feel like I still need to get good at them since they could really help in the future.
The problem is, I really don't know how I could motivate and force myself to keep on learning and improving myself.
Also, I'm afraid that by putting too much attention on this, I will start lacking at another area.
Joanna, have you tried finding a teacher who teaches you on a regular basis? That way there is another person who can keep you accountable to your language learning goals.
