My take is that Trump is a Big Picture Guy - he laid out what he wanted and then trusted Ryan to do his job by putting it in a bill and rallying and managing a coalition to get it through the House. Despite the fact that everyone wanted Healthcare reform, he failed miserably on ALL points!
Now Tax reform takes the stage, and because Healthcare Reform fell on it's face, there will be the tendency to want to rush this through to get a victory. Some salient points:
The Groundwork must be laid early, by recruiting a coalition, who then can recruit other members. NOT depending on the immature "Speaker" who has few allies and who throws something together, keeps it secret, and refuses to make changes because it hurts his ego.
Don't expect the dems to sign on, no matter how good the plan is. The strategy under Pelosi and Schumky Schumer is to oppose EVERYTHING Trump does, even if the Country suffers. The Deep State strategy is to make him fail and possibly get him to resign.
Don't trust, or count on Ryan for ANYTHING. His loyalties are suspect, he's immature, not respected or well liked, and a total incompetent. I can't think of a single thing he's managed and gotten through, even with a GOP majority.
If you want a good tax reform, there a Constitutional amendment (suggested here) which reads:
Tax Reform Amendment Section I
No tax, fee, fine, or judgement —federal, State, or subdivision of either— shall ever be withheld from any wage.

No property shall be seized for failure to pay taxes until after conviction in a jury trial; the right of the jury to nullify (and thereby forgive) this debt shall never be questioned or denied.
Section III
The second amendment is hereby recognized as restricting the power of taxation, both federal and state: no tax, fee, or fine shall be laid upon arms, munitions or the sale thereof.
