Is Learning and Memorizing Chinese Characters much different than English?
Chinese characters and phonetics
You say:

Unlike English, Chinese is not a spelling language, which means there is no hint from the characters for pronunciation!!!

Luckily for us, that's not true! Actually, by some estimates, almost 90% of characters have a phonetic component to them. To understand what that actually means, you have to know how characters are constructed:
Types of characters
There are several ways in which characters are constructed. Westerners often exoticize and obsess over 1-3 and don't realize that 4 and 5 exist (and indeed, 5 makes up the vast majority of cases).

Pictograms -- These are visual representations of the morpheme they stand for. Of course, given how old these characters are, the modern forms are highly stylized, to the point of unrecognizability (e.g., 马 = horse). These are not common.

Simple ideograms -- These are iconic representations of abstract concepts (e.g., 二 = 2). Most uncommon category.

Compound ideograms -- These are juxtapositions of pictograms and ideograms, where the meaning is supposed to be inferred from that juxtapositions (e.g., 人 [man] + 木 [tree] = 休 [rest]). These are also not common.

Rebus characters (phonetic borrowings) -- It turns out that you can't actually draw pictures of all concepts. If you want to have a writing system where you can actually write down anything, you need to make reference to the spoken language. A common strategy (used in every independently invented system of writing) for getting around the limits of pictograms is the Rebus Principle: use existing symbols purely for their sounds regardless of their meaning. Chinese example: 來 (to come) originally was a pictogram of wheat, a word that had a similar pronunciation. You may also be familiar with rebuses in the context of amusing puzzles.

Phono-semantic characters -- It can be confusing to have two different morphemes written with the same character. Many phonetic loans were &quot;clarified&quot; by distinguishing the two usages by adding a semantically-suggestive piece. For example, 皇 (pronounced &quot;huang2&quot;, meaning &quot;emperor&quot;) and 蝗 (pronounced &quot;huang2&quot;, meaning &quot;locust&quot;, has the &quot;bug&quot; radical). The vast majority of characters are of this type. Unfortunately, the phonetic parts are often approximate or even poor.

It is different. Like I explained above, it's often the case that you can guess (or at least remember) the pronunciation of characters based on the pronunciation of other characters. Also, like I said, phonetics are far from perfect. There has been thousands of years of sound change working to make once-great phonetics bad. If you want to learn Chinese characters, it's going to be a lot of work, no matter how you slice it. Start with the basics, and once you work up to several hundred of them, you'll start understanding some of the patterns, both in terms of semantic radicals and common phonetic components.
