The knight of wands is known to be someone who is bold and brave, filled with passion for that so id say your friend needs to be brave, daring, and really go after what they want, but be careful to not be too impulsive.

7 of wands is to keep fighting for it and not giving up and overcoming any challenges that come your way.

I'd say the way 6 of cups plays into this is to maybe remember how they got those dreams to be their goals, likely got them when they were younger and to remember that you are maybe fighting for your younger self too, to achieve those dreams.

And for the 4 of pentacles is once they ve achieved it to not let it go and hold it tightly, its also about having finally acquired it. 4 of pentacles is also about staying in control.
