You can take responsibility for not always feeling good. It’s no big deal if you can not keep up with others and have less stamina than you expect. It’s better to listen to your body’s signals and take a short break rather than squeezing too hard and risking fatigue.
If your work is criticized especially hard. Immediately develop a comprehensive plan to improve your situation and get the job done. Do not be too cautious about your plans, make others aware of what you want to achieve, and get valuable tips and support from them.
In your relationship you are everywhere and nowhere. There have not been any real key points and your partner is more fascinated by the sky than you. So be honest with yourself and be open minded about what went wrong and where you both run out of steam! Try to tackle the root of the problem and work with your partner.
