Tomo Fujita Guitar Wisdom

i've been playing guitar for a year and a half, mostly learning from the internet, and recently i feel kind of stuck, so i subscribe this lesson from matser tomo, and i got some questions:

(1) i'm kind of familarize with the fretboard (only C major scale, no accidentals), it normally takes me about 1 second to work out what the note is. So how well should i know the fretboard? Is this enough for me to start learning triads or some other stuffs?

(2) i'm kind of familarize with triad already, i know the degrees of the notes within the triad, and i mostly loacte the triad by knowing where the next root note is, and then build the whole triad based on their intervals , is this the right way to learn triad? i 've watched the first 2 videos in "foundation - triad", but i still have little idea about what should i be thinking when i'm going to play the next triad

(3) i've been doing some ear training for a while, i can identify the 7 intervals (M2, M3, P4, P5, M6, M7, Octave) from the major scale, and i've been singing and praticing solfege for some time, but i am still having a hard time to dictate a melody, normally when im doing this, i find out what the "tonic - do" is first, then i compare ervery other notes to the tonic individually to find out what their degrees are.Is this the right way to dictate a melody?

Here is Tomo's comment:

"Thanks so much for subscribing to my Guitar Wisdom. Learning from the Internet is a bit dangerous, because only about half the information is accurate. The other half will keep you stuck in the same place for years, no matter how many hours you study and practice. So, I created Guitar Wisdom to teach the elements that will help you to move forward.

"(1) Do not memorize the fretboard! Memorization is quick, but you need to know notes, intervals, scales, triads and 7th chords, and these take time. How much time? Each person is different. Take your time. Don't worry! Don't compare! Don't expect [to progress] too fast! Be kind to yourself!

"(2) Good job on triads! Just don't rely on playing from the Root each time. You need to know triads from the Root, 3rd and 5th. Sing them, before you play them. Think about sounds, rather than shapes. Always be humble and ready to learn more!

"(3) Good job! Now try changing keys. Move to D. Can you sing Root to 4th without difficulty? Change to the key of Eb. Can you hear the M7 right away? If not, keep working! This is very important. At Berklee, we teach Ear Training three times each week for four semesters.
