Just off the top of my head....
Biggest hopes, in order of confidence it will actually happen:
1. Be an unabashed promoter of American Exceptionalism and cheerleader for the US, economic surge
2. Replace Scalia and at least one liberal justice with Scalia clones, appoint conservatives to federal courts
3. Undo Obama executive orders (might be easiest to just wipe the slate clean)
4. Scrap Obamacare
5. De-politicize enforcement of federal law (Jeff Sessions!)
6. De-regulate and de-subsidize domestic energy production
7. Significantly reduce illegal immigration
8. De-politicize the IRS
9. Withdraw from climate pacts
10. Disband or at least dramatically diminish the mandate of EPA, Education, HUD, and various other federal agencies.
11. Defund Planned Parenthood and other abortion providers
12. Simplify tax code, maybe even reduce tax burden on HENRY's like me
13. Reduce spending
Biggest fears:
1. Assassination
2. Major terrorist attack, scuttling domestic agenda
3. Rely too heavily on executive orders, like Obama, because the GOP legislature can't get its act together
4. Bungle the repeal and replacement of Obamacare, because the GOP can't get its act together
5. A $1 trillion infrastructure bill and other wasteful spending that continues massive deficits
6. Waste way too much money building a wall instead of simply enforcing federal immigration law
7. Cabinet and agency appointments are overwhelmed by the bureaucracy, little meaningful reform
