1down Highly-motivated person (4-7)
I have s?l?s?a?t?r. (Self-starter is the only thing I can think of, but to me this doesn't 'feel' right.)
It's the last one to solve! Thanks in anticipation for all help.
self-starter
noun
1.
a person who is sufficiently motivated or ambitious to work on their own initiative without needing direction.
"he was the self-starter who worked his way up from messenger boy to account executive"
Even though I didn't think it was correct, it was the only answer that fitted! Very many thanks for your input Mamya. I'm always learning something new by doing these crosswords!
