Everyone makes goals to learn new things. Sometimes it's hard to meet your goals, and it feels frustrating. Some teachers in the U.S. have a system they call SMART. They say learning goals must be
S - Specific
M - Measurable
A - Achievable
R - Realistic
T - Timely
'Specific' means 'exact'. Not "I want to learn English", but "I want to improve my spelling".
'Measurable' means you can measure your success. For example, "I learned to spell 6 new words this week."
'Achievable' means you can achieve, or succeed in meeting your goal. Not "I will learn to spell 1,000 new words this week!"
'Realistic' is similar to 'achievable'. You really can meet your goal if you try.
'Timely' means it's a good time for you to try this. For example, spelling is important to you now because you need to improve your writing for work. At another time, it might be more important to work on your speaking skills.
When you set SMART goals, you will feel successful. You can learn English (or anything!) one step at a time. Good luck!
