Try not to convince yourself that you have more to prove to someone than you do. But the word 'prove' might be a bit inaccurate. 'Reassure' is probably better. When it comes to being talked out of doing something that you know, in your heart, you must do, you could excel at doing so better than anyone else. By summoning courage, you could remind - and reassure - yourself of something you can do that you may have convinced yourself that you can't.
Success, in many ways, comes down to timing. This could be particularly true when we must ask something of someone. Kids learn to do this from a young age. But when it comes to raising sensitive topics for discussion, well, we need to choose our time even more cleverly. Now is as good a time as any to bring a sensitive issue into the open. Don't delay this discussion in the belief that a better time must be found to have it.
Improving your productivity could require you to assess closely the environment in which you work. If it becomes clear that distractions or clutter prevent you from getting through your To-Do List properly and effectively, then you have a chance to address this and make improvements. If you want to shine in others' eyes, then you'll need to bring structure to what is done erratically or chaotically.
